Which of the following technical selections would be most appropriate when applying a breathing technique to the lateral thoracic spine?

75 kVp at 400 mAs, and 1 second
75 kVp, 100 mA, and 3 seconds
75 kVp, 200 mA, and 4 seconds
75 kVp at 200 mAs and 1 second


75 kVp, 100 mA, and 3 seconds

Rationale: Breathing technique requires that the mA and time be set independently. For a breathing technique to be effective, a time of 3-4 seconds must be established. The lower mA station applied with the time will help reduce the patient dose.
